Concrete pumping agent is a traditional product with stable quality produced by our company. It is composed of naphthalene sulfonic acid condensation polymer as the main component and compounded with retarding, waterproofing, water-retaining and other components with waterproof function. Concrete composite pumping agent. It can effectively reduce the loss of concrete slump over time, improve concrete pumpability and compressive strength at all ages, and achieve the purpose of waterproofing concrete and completing pumping in one go. Over the years, this product has been well received by users for its outstanding performance, especially in the construction of highways, railways, and power stations. All technical properties of the products meet the national standards for first-class products.
1. Necessary concrete tests should be conducted before using the pumping agent to examine its adaptability to cement and determine the dosage. It can be directly dispersed in cement and the mixing time can be extended to more than 1 minute. The post-mixing method can also be used, that is, the concrete is mixed with part of the mixing water before adding this product for better results.
2. During high temperatures in summer, sand and gravel contain less water and absorb more water, which is not conducive to concrete pumping. Therefore, attention should be paid to ensuring that the "dry sand" must be moist and the "sub-stone" must be hydrated, so as to facilitate long-distance pumping of concrete. The dosage with low strength level and short pumping distance can be reliably off the line or the recommended dosage. On the contrary, the dosage depends on the upper line. When preparing high-strength self-leveling or high-impermeability waterproof concrete, the water-cement ratio should be reduced to reduce the slump. (It should be 100-150mm).
3. The powder of this product is packed in 30kg/bag woven bags, stored in a dry place and protected from moisture. The shelf life is two years. If it exceeds the expiration date or becomes agglomerated due to moisture, it can be used after passing the inspection.
